An electronic device is provided to prevent an integrated circuit and an electronic component on a printed circuit board from being damaged due to ESD(Electrostatic Discharge) by connecting a voltage clamping unit between a conductive connection unit and a metal shield. A case(100) forms an outer appearance of the electronic device. A metal shield(200) is formed inside the case in order to shield the electromagnetic wave. A printed circuit board(300) is arranged inside the metal shield. The printed circuit board has a ground layer. The integrated circuit and the electronic component are mounted on the printed circuit board. A plurality of conductive connection units(220) are formed in the metal shield in order to electrically connect the metal shield and the ground layer. A plurality of voltage clamping units(260) are connected between the conductive connection part and the metal shield. The plurality of conductive connectors(240) are formed in the metal shield. |
